  Maybe we need //Comment comment

Do we need comment in our programs? Depends, if we can write a program which can clearly tell s the reader what the program does, then we had better to avoid unnecessary comments. However, if the program we develop is complex enough and it involves some uncommon logic which needs more explanation, then we have to add comment and make sure the comment we add can correctly tell the readers what we do. The worst scenarios is not you forget or you don't want to add comment, it's that you add comment...

  A Baseline for Front-End Developers

I wrote a README the other day for a project that I’m hoping other developers will look at and learn from, and as I was writing it, I realized that it was the sort of thing that might have intimidated the hell out of me a couple of years ago, what with its casual mentions of Node, npm, Homebrew, git, tests, and development and production builds. Once upon a time, editing files, testing them locally (as best as we could, anyway), and then FTPing them to the server was the essential ...

  Difference between Beijing and Silicon Valley on innovation

The fundamental difference between Beijing and Silicon Valley is not the sky color, but the fact that on one side the young people are talking about buying a new house, a new car and getting married, while on the other side young people are talking about how to change the world. Now and then we can read from the newspaper or the Internet that a Silicon Valley company is valued over 1 billion US dollars. Also we can see many famous US IT brands on the Internet such as Google, Facebook,Twitter, Am...

  How regular expression works

Rob Pike wrote 30 lines of codes to realize a simple regular expression matcher in his book The practice of Programming. This piece of code is really cool. Let's take a look at the code.Meaning of different characters.Character Meaning c General character . Match any single character ^ Match start of a string $ Match end of a string * Match zero or many occurrences of a character /*match ：Test the regexp in text*/int match(char* regexp,char* text){    if(regexp[0] == '^')&n...

  C++ Versus Objective-C

What will programming in Objective-C mean to the C++ programmer Different Object Oriented Languages Almost all of us have heard the term object oriented programming, and most of us have used C++. How will Apple's purchase of NeXT, and NeXT's framework using Objective-C affect us as we develop software? If we know C++ already, how hard will it be to get up to speed on Objective-C? Many people will agree that once they understand the concepts of object oriented programming it doesn't matter...

  GitHub Copilot may generate code containing GPL code

GitHub Copilot is a new AI-powered code completion tool that can generate code snippets from natural language descriptions. It is powered by OpenAI Codex, a deep learning system that has been trained on billions of lines of public code. GitHub Copilot claims to be a “copilot, not a pilot”, meaning that it is not intended to write code for you, but rather to help you write code faster and better. However, some developers have raised concerns about the legal and ethical implications of...

  A Perl Regular Expression That Matches Prime Numbers

perl -lne '(1x$_) =~ /^1?$|^(11+?)\1+$/ || print "$_ is prime"' Can you figure out how it works? I give an explanation below, but try to figure it out yourself. Here is what happens when you run it: $ perl -lne '(1x$_) =~ /^1?$|^(11+?)\1+$/ || print "$_ is prime"' 1 2 2 is prime 3 3 is prime 4 5 5 is prime 6 7 7 is prime 8 9 10 11 11 is prime Here is how it works. First, the number is converted in its unary representation by (1x$_). For example, the number 5 gets converted into 1x5, which is ...

  Learn from Haskell - Functional, Reusable JavaScript

Learn You a Haskell: For Great Good? For the last couple months I have been learning Haskell. Because there are so many unfamiliar concepts, it feels like learning to program all over again. At i.TV, we write a lot of JavaScript (node.js and front end). While many functional/haskell paradigms don’t translate, there are a few techniques that JS can benefit from. There are Haskell library functions for everything. At first I thought this was just because it was mature, but then I notice...
